I am thinking about picking up one of the cheaper standard Leica R lenses and adapting it for use with an older DSLR. I have only ever used very old Leica lenses in my Bessa R rangefinder systems, mostly uncoated. I use a lot of old equipment and rather like my Zeiss uncoated medium format folders from almost 80 years ago. After repeated use I understand their limitations, quirks and the results they produce. I barely shoot digital these days and have a meagre Sony A100 DSLR. I shoot adapted Minolta and Zeiss lenses using this setup and the results are pleasing for me. Manual focusing does not bother me. Manual metering does not bother me. Exposure compensation does not bother me. Not even stop down metering dampens my spirit! If I were to get the cheapest of Leica R lenses and use it on my crop frame DSLR, should be I wowed by Leica's optical quality? I won't not be able to afford a digital Leica for a number of years - well, I don't know when. I can only save up and buy one Leica lens so it is important that it would give me something that I can't have at the moment. What is that something? Perhaps the pleasure of using coveted glass and the expectation of slightly better quality that what I get at present. I like the idea of shooting wide open as well!
